#QUCS MANUAL PORT EDIT SIMULATOR#

I will provide a brief tutorial of Qucs – Quite Universal Circuit Simulator which is an open-source circuit simulator being developed by The Qucs Development Team – a multi-disciplinary group of talented engineers, scientists and mathematicians. This post will cover the installation and use of Schematic Capture and Circuit Simulation tools. Today I’ll be discussing the Knowm Open-Source EDA Stack that includes Knowm contributed extensions to popular open-source EDA tools to be used for the design, layout, and simulation of memristor devices and neuro-memristive circuits.

Not sure about other Spice simulators, but LTSpice add as default series resistances to inductors, which at this high frequency can make a difference due to its lower quality factor.In a previous post titled Knowm Memristor Modeling and Simulation, I presented the implementation of a Verilog-A version of the Knowm MSS model within industry standard commercial EDA tools.Sampling points are too small, meaning that the points in between are interpolated.Simulation and mathematical method do not use the same amount of sampling points.

As for the discrepancies in the original question, I could think of the following ones: I have numerically calculated both examples using octave/matlab and LTspice, and both show at first sight the same results: P.S.: If you have a more accurate title, please feel free to change it! Question: Does anyone have any new (see above) ideas or suggestions? I tried using more physical models for the capacitor (by adding inductive and resistive elements), but to no avail. I checked time and again if the RFsim-Software has some 'more physical' model for it's components, but since you can explicitly turn these off and on (and I have them turned off) and the manual doesn't say anything, I strongly believe, that it should be an 'ideal' model. What I've tried so far: I tried several things like adding series 50𝛺 'resistors' to emulate the admittance of the ports I checked weather my chosen language (python) handles the inversion of complex numbers well and it does. I am wondering where the discrepancy could come from. This small, but not negligible discrepancy can also be seen in slightly more complicated circuits, like a simple resonator circuit (see below).

This gave me something which is very similar to what I'd expect:īut if I compare that with a very simple software (RFsim99, all ideal models) The way I implemented this is the following (pseudocode): Z0 = 50 The first circuit I attempted the simplest example of just a capacitor: I want to be able to simulate simple (idealized) RF circuits, such as resonators, filters etc, in a self-written program (I currently use python). Hadn't even considered that as an option. TL DR: Why does the (pseudo-)code below produce a different output than a proper simulation software?Įdit: -> Answer: The program (RFSim99) displays only abs, not squared (which is what I plotted).
